MICROCHIP MCP1700T-3002E/TT Fixed 3V LDO Voltage Regulator, 250mA

The MICROCHIP MCP1700T-3002E/TT is a CMOS low dropout (LDO) positive voltage regulator, engineered to deliver up to 250mA of current with exceptional efficiency. Its standout feature is an extremely low input-output voltage differential of just 178mV at the full 250mA load. This minimal dropout voltage, combined with an ultralow quiescent current of only 1.6µA, makes it perfectly suited for battery-powered applications, significantly extending operating life by maximising usable battery capacity.

Designed for reliability, the regulator incorporates both short-circuit and over-temperature protection, safeguarding the circuit and the device itself under fault conditions. It remains stable with only a small 1.0µF ceramic output capacitor, simplifying design and saving board space. This combination of low dropout, low power consumption, and integrated protection allows for high current delivery from compact packages, even with minimal voltage headroom.

Key Features and Benefits

• Extended Battery Life: The extremely low 1.6µA operating current and 178mV dropout voltage minimise power waste, allowing batteries to last longer.
• High Accuracy: Provides a precise 3V output with a typical accuracy of ±0.4%, ensuring consistent performance for sensitive electronics.
• Robust Protection: Integrated overcurrent and over-temperature protection enhance system reliability and durability.
• Design Flexibility: It is a pin-compatible upgrade for older bipolar regulators and the TC55 series, facilitating easy design improvements. Its surface-mount SOT-23-3 package is ideal for space-constrained applications.
• Stable with Minimal Components: Requires only a 1µF ceramic output capacitor for stability, reducing bill-of-materials cost and complexity.

This regulator is an excellent choice for designers seeking a reliable, efficient, and compact power management solution for a wide range
